Inclination not force is sensed by plants during shoot gravitropism [PDF]
, 2016 International audienceGravity perception plays a key role in how plants develop and adapt to environmental changes. However, more than a century after the pioneering work of Darwin, little is known on the sensing mechanism.

Frontiers in Plant Science, 2020 When positioned horizontally, roots grow down toward the direction of gravity. This phenomenon, called gravitropism, is influenced by most of the major plant hormones including brassinosteroids. Epi-brassinolide (eBL) was previously shown to enhance root

Complementation of the embryo-lethal T-DNA insertion mutant of AUXIN-BINDING-PROTEIN 1 (ABP1) with abp1 point mutated versions reveals crosstalk of ABP1 and phytochromes [PDF]
, 2014 The function of the extracytoplasmic AUXIN-BINDING-PROTEIN1 (ABP1) is largely enigmatic. We complemented a homozygous T-DNA insertion null mutant of ABP1 in Arabidopsis thaliana Wassilewskia with three mutated and one wild-type (wt) ABP1 cDNA, all tagged

Plant Gravitropism and Signal Conversion under a Stress Environment of Altered Gravity
International Journal of Molecular Sciences, 2021 Humans have been committed to space exploration and to find the next planet suitable for human survival. The construction of an ecosystem that adapts to the long-term survival of human beings in space stations or other planets would be the first step ...

Root Meristem Maintenance Mechanisms are Key to Plant Defense Against Nanoplastics
Advanced Science, EarlyView.Small nanoplastics can disrupt cell integrity and inhibit cell division in meristem zone of plant root. The plants can counteract the cell damage by upregulating genes associated with root meristem maintenance and increasing auxin accumulation by PIN2 transport inhibition.

Single-cell-based system to monitor carrier driven cellular auxin homeostasis [PDF]
, 2013 Background: Abundance and distribution of the plant hormone auxin play important roles in plant development. Besides other metabolic processes, various auxin carriers control the cellular level of active auxin and, hence, are major regulators of cellular

Evolution of fast root gravitropism in seed plants
Nature Communications, 2019 An important adaptation during colonization of land by plants is gravitropic growth of roots, which enabled roots to reach water and nutrients, and firmly anchor plants in the ground.

Polar‐localized EXO70G1 regulates root development in Arabidopsis thaliana
Journal of Integrative Plant Biology, EarlyView.The putative exocyst subunit EXO70G1 exhibits apical‐basal polarity in Arabidopsis root cells; this polarity stabilizes membrane domains to facilitate targeting of the auxin transporter PIN‐FORMED2 during root development. ABSTRACT Cellular asymmetry, which represents a fundamental characteristic of cell polarity, is prominently illustrated by the ...

Plants, 2019 Stem straightness is related to wood quality and yield. Although important genetic differences in stem straightness among the natural populations of Pinus pinaster are well established, the main drivers of these differences are not well known.
